    Von Neumann entanglement entropy \(S_A\)  of a subsystem \(A\) , in two spatial dimension, measures the entanglement between the subsystem \(A\)  and the rest. In a general system, this measure \(S_A\)  is dependent on the geometry of the subsystem \(A\) . Topologically order systems are special calls of systems. This entanglement measure \(S_A\)  has a piece that depends on the topology of the subsystem \(A\)  and the topology of the underlying manifold, called Topological Entanglement Entropy (TEE) [1]}, [2]}, [3]}, along with a geometry dependent piece. Symbolically
\(S_A=\alpha L_A -\gamma _A~,~~\gamma _A=\mathcal {J}_A \Omega \)
